Gyprock Perforated Plasterboard has been designed for use on ceilings and walls where increased levels of sound attenuation is required.

As the name implies, the acoustic properties of the board are achieved by perforations to approximately 8% of the board surface that absorb sound to reduce echoes and reverberation. The long edges of the panels are recessed for flush jointing to a smooth, continuous surface.

Gyprock Perforated Plasterboard is manufactured in Australia to Australian Standard AS2588 and the heavy-duty face paper is a buff colour.

Controlled Density Technology (CD)

Gyprock Perforated Plasterboard is made up of a gypsum plaster core that is wrapped in heavy-duty linerboard paper with bonded edges. Controlled Density technology allows the board’s core structure to be manipulated. CD technology produces a core structure that is denser at the faces of the board with a gradual increase in aeration towards the centre of the core.

Controlled Density technology delivers a number of important benefits:

Plasterboard Installation

AS/NZS2589: Gypsum linings – Application and Finishing outlines the procedures for the installation and finishing of Gyprock Perforated Plasterboard in conjunction with additional details contained in Gyprock Technical Literature.

Levels of Finish

A Level of Finish sets out the minimum specifications for installation processes from framing preparation to painting and decoration. The levels are defined in AS/NZS 2589.1, and are intended to provide builders, installers and homeowners with defined methods and practices necessary to meet expectations in terms of the Level of Finish. They are not applicable to fire rated construction.

The level of finish should be specified prior to construction as it can be affected at different stages of construction and tolerances must be adhered to:

Frame construction

Plasterboard fixing and back-blocking

Plasterboard jointing and setting

A Level 3 Finish is for areas that do not require painting and decoration such as above ceilings and inside service shafts.

A Level 4 Finish is the generally accepted level for domestic construction

A Level 5 Finish should be specified wherever gloss, semi-gloss or dark coloured paints are to be used, or where critical glancing light conditions are likely.
